CASING-LOCK FOB ROLLER-BEARINGS.

Specification of Lettersiatent. I

Be it known that I, CHARLES wooo, a citizenof the United States, residing at 289 Market street, Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improve ments in Casing-Locks for Roller-Bearings, fully described and represented in thefollowing specification and the accompanying drawings, forminga part ofthe same. I

. This invention relates to that 'class of roller-bearings in which a hub is provided with seats for two sets of tapering rolls and the casing is provided with two seatsto engage the'outer sides of the rolls, and one of such seats is adjustable to and from the other to fit the same accurately to the outer circumference of the rolls..-

It is common in such casings to fix one" seat rigidl within one end of the casing and to malZe the other adjustable by screwing it into the opposite end of the casing, and the object of the present invention is to furnish an efiicient and economical means of locking the said movable seat in position. when adjusted. In the present invention,

this is effected by providingthe inner edge of the adjustable seat with a continuous- The casing is constructed with an annular space between the stationary and movable seats, and the spring ispreferably made of a flat barextended half .way around the interior of this space and having one end secured to the casing by two rivets, with the tongue upon the opposite end extended into the notches of the adjustable 'seat. A slot is formed in the casing transverse to the spring adjacent to the tongue, and a.

stud is projected from the tongue through the slot so as to be readily manipulated by the fingers from the outside of the casing.

The outer end of the stud is not con-.

structed to project beyond the periphery of the casing, and the invention is thus applicable to that class of self-contained roller-bearings which have a cylindrical exterior adapted to fit in a socket in any part of an automobile or other mechanism, as

rack-teeth between the rack-notches.

- there is no projection upon its exterior to s. Lt

interfere with its fitting into such a, socket.

ten ed within the casing in opposite'directions and embracing opposite sides oftlie This construction resists any movement of the adjustable seat more rigidly, as the curved spring resists rigidly any pressure directed toward its foot, but not in' the other direction which 'tends to straighten the spring .and loosen itifrom the interior of the casing.

Where a single spring is used, the stud must fit the casing-slot snugly so that the stud may resist circumferential pressure; but where twosprings are used the thrust of the; adjustable seat upon .each spring is toward the foot of the spring, and the teeth upon the seat are held rigidlyregardless o the stud. Where a. single spring is used a certain movement of the rack-teeth would eXtend't-he spring and tend to draw it from its seat, and thus permit some motion'ofthe ring e, but where twosprings are used one o'r-th other operates positively to hold the ring 6 ri idly.

The seats d and c are of collar form, and the seat c'is provided with holes 9 upon its outer side to which aspanner ay be applied for turning. the seat in the casing.

Such bar-spring it fitted to the interior of the casing between the seats d and e and is shown in Fig. 3 extending half Way around the same, and it is 1 provided, as shown in Fig. 2, with a square tongue at to fit the notches i, and thus tion; The head of the spring adjacent to the tongue n is perforated to receive astud.

When the desired, ad-

' I the seat that an almost infinitesimal adjust-.

' ment can be effected. and the nearest notch turned to engage the tongue without impairing the adjustment required. v

Fig. 7 shows two springs k'and k having their heads each overlapping half the width of the transverse casing-slot p, and provided with similar coinciding slots 7' to both of which the shank'c of the stud is fitted, by flattening the same, as shown in Figs. 9 and .10. The bars of the two springs extend in opposite directions from the stud nearly half way around the casing, with their feet I riveted thereto, The heads of these two earner springs are not constructed with a rectangular tongue to fit both sides of the notches i of the adjustable seat, but are formed each with a tongue n sloped toward the end of I the spring-bar and adapted to engage opposite sides of the teeth .which lie between the notches 2'. Any tendency of the seat to rotate in either direction thus produces compression upon the bar of one or the other spring by longitudinal pressure, and. no movement has any tendency to extend the spring or draw it from contact with the interior of the casing, as the tongue upon each spring holds the adjustable seat positively and rigidlyifrom rotation in one direction. When a single sprin is employed, the stud is preferably riveted Fig. 1, but it-may be operated by fitting the flattened shank of a stud to a slot in its head the stud has no restraining influence upon the end-movement of the tongue, for which reason when asingle spring is used and the tongue required to resist motion in both dithereto, as shown in .rections, it is preferable that the stud should be secured rigidly to the head of the spring and fitted snugly to the casing-slot, thus' preventing any circumferential movement oft-he tongue. The cross-section of the barspring is immaterial provided it'has a body of sufficient stiffness and length sufiiciently' great to give to it the flexibility desired.

I am aware that it. is common wherecircular parts are movableupon one another to provide the parts respectively with ratchet-teeth and a spring awl of some kind; but my construction di ers fromthese in the projection. of a stud from the head structive features which make the lockingdevice more effective.
